400道四年级上册的脱式计算并有答案。
1、92+92×99 解析:此题可以利用乘法结合律,将1与99结合,组成100,再与92相乘,使得运算简便。 92+92×99 =92×1+92×99 =92×(99+1) =92×100 =9200 2、6.07+0.4-0.08 解析:此题的小数之前没有规律不方便计算,可先利用分配律把0.08转换成0.07+0.01,再利用加法结合律进行简便计算。 6.07+0.4-0.08 =6.07+0.4-(0.07+0.01) =6.07+0.4-0.07-0.01 =6.07-0.07+0.4-0.01 =6+0.4-0.01 =6.4-0.01 =6.39 3、8.2-9.6x0.5 解析:此题先计算乘法,再计算减法,脱式算法如下: 8.2-9.6x0.5 =8.2-4.8 =3.4 4、35x62+70x19 解析:此题先利用乘法分配律把70变换成35成2,再利用乘法分配律的逆运用提取公约数35,最后利用乘法结合律来简便计算。 35x62+70x19 =35x62+35x2x19 =35x62+35x38 =35×(62+38) =100×35 =3500 5、24.6-3.98+5.4-6.02 此题利用加法交换结合律,凑整再计算。步骤如下: 24.6-3.98+5.4-6.02 =(24.6+5.4)-(3.98+6.02) =30-10 =20

『捌』 小学四年级下册数学脱式计算题怎么算的
脱式计算,即递等式计算,把计算过程完整写出来的运算,也就是脱离竖专式的计算。在计算混合运算时属,通常是一步计算一个算式(逐步计算,等号不能写在原式上),要写出每一步的过程。一般来说,等号要往前,不与第一行对齐。也就是离开原式计算。
主要掌握的是记住要先算乘、除法,后算加、减法。在乘除法连继计算时中,要按从左往右的顺序依次计算。遇到括号,要首先计算括号内部。在脱式过程中要按运算顺序划出运算顺序线,还要做到“三核对”:一、要核对从书上把题抄到作业本上数字、符号是否抄对;二、要核对从横式抄到草稿竖式的数字、符号是否抄对;三、要核对把草稿竖式上的得数,抄到横式上是否抄对,小数点是否点对地方,有无遗漏。
